The Honeywell Pro Series Review – The Best Smart Thermostat for Your Home

Honeywell Pro Series

In the early years, the original smart thermostats that were released into the market took the whole globe by storm. These thermostats had a very ultra-modern style and users were given the ability to connect to the Wi-Fi.

Many were impressed by the device that could find out your daily routine and accordingly generate both cooling and heating timetables. If you would like to smarten up your house, your thermostat is definitely a good place to get started.

With a thermostat, you can easily save a good amount of money by reducing the money spent on heating and cooling. You should note, however, not all thermostats are manufactured in the same way. Some thermostats are made for basic cooling and heating electric systems.

More reasons why you should go for the honeywell pro series?

These thermostats provide you with normal programming and scheduling possibilities, while other thermostats are manufactured to provide multiplex stage systems. This manages the ventilation, dehumidifier, cooling and heating systems. This is the case with a number of smart home equipment. 

The most ideal smart thermostat has an exterior impact on how comfortable you feel in your own house.

It also influences your home budget. Getting yourself a thermostat that you can program can easily help cut down on the cost. This is done by switching on your AC when you are expected to be in the house and switching it off when you’re not around. 


If you would like to modify your home and change it to a smarter house, purchasing a thermostat is a great place to begin. As mentioned earlier different thermostats are designed with different capabilities and functions. That is why the price of each thermostat varies.

This guide will give you an idea of what you should expect from your thermostat. If you are in the market looking to purchase a thermostat for your home, this review will guide you through the whole process. 

The Honeywell Home T9 Thermostat Pro Series

    Honeywell Pro Series

In the thermostat market, what sets apart the top thermostat models from the others in the field is the thermostat potential to estimate the temperature and condition in more than just one spot around your house.

This function allows the user to easily balance the cooling and heating operations in the places where you are actually occupying, instead of only regulating the conditions in areas where the thermostat has been mounted.

This is almost as awesome as having a number of zoned air conditioning, ventilation and heating systems. 

To achieve these functions, smart thermostats make use of small wireless remote sensors that can easily become aware of temperatures and then combine that data and information into their findings. The Honeywell Home T9 is designed with a consumer thermostat.

Thermostast functions

This thermostat aids the remote temperature sensors.

Not only can this tool measure the temperature and detect an individual’s presence in a room, but the Honeywell Home T9 also has sensors that can measure the humidity in a room. 

The T9 series is equipped with a number of features that you would expect a smart thermostat to own.

This includes the support of a number of HVAC (heating, ventilation and zoned air conditioning system.), geofenced scheduling or time-based as well as a smartphone app that can control your system whenever you’re not in the house.

This thermostat also gives support to both Google Assistant and Amazon’s Alexa assistant for voice control. 

If you would prefer to combine it with a number of other smart home products, the Honeywell T9 series is compatible with IFTTT as well as Samsung’s SmartThings.

This feature definitely gives it an edge over other thermostats in the market. 

Installing the Honeywell Home T9 Thermostat

Setting up the T9 is almost the same as installing all the other smart thermostats in the market. You will have to first combine the wires from your old thermostat to where they will have to go onto your new thermostat.

If you own a very complex system, you will have to make use of extra wiring or take more time putting up the Honeywell T9 thermostat. If you would like to find out if your device can work well with your Honeywell T9, you can make use of the Honeywell Home website.

This website has a whole compatibility checker. Before you make the decision to purchase this smart thermostat, you can use this checker to confirm if the T9 series will work well for you. 

The T9 smart has a shape that is very different from many other contemporary thermostats. The T9 denotes a vertically oriented rectangle shape. This makes it more narrow than tall.

Feedback from users

Some users have stated that the T9 could not cover up all the holes from their old thermostats. So, it all depends on the shape of the thermostat that you are currently using.

Some people may have to perform some repair work as well as paint the wall. The T9 smart thermostat was specifically designed to cover up the holes from the older Honeywell thermostats. 

Other than that, the Honeywell T9 series has an ultra-modern and attractive design. It also comes with a very big, color touchscreen display that is really bright making it easy to read even from across the room.

When the AC has been turned on, the thermostat will turn the screen’s background blue and when the heat is on, the background of the screen will turn bright orange.

In this way, you can easily see what operation your screen is performing simply by glancing at the screen. The touchscreen is also really easy to use. The functions provided are very quick and responsive.

Extra Features

The T9 thermostat also comes equipped with a remote sensor that is really large and it can also be mounted onto a wall. The remote sensor does not have a stand which means that you can easily place it on a mantle or a shelf.

The box also has 3M strips that come in really handy because mounting the sensor becomes really easy. 

One of the great advantages of the sensor is the fact that it works well with two contemporary AAA batteries.

These batteries are so easy to use and replace than the coin-cell batteries or the lithium battery that is used by many other sensors. The AAA batteries can last for up to a year even when used normally. 

Measuring Temperature and Humidity

As stated earlier, the T9 sensors can easily estimate temperature as well as humidity. These are functions that other contemporary sensors cannot perform. The sensor can also detect presence and motion.

This means that it can modify the system to only work in rooms where people are actually occupying. 

This thermostat also enables you to choose which sensor you would like to read from in a certain time frame, and it will give an average of the system’s temperature according to many readings. The thermostats’ single sensors can also be acknowledged by using Google Assistant and Alexa.

This feature allows users to make use of voice commands that place the thermostat according to specific sensors. This feature also cannot be found in other contemporary thermostats. 

How to use the T9’S scheduling functions

To use the T9’s people detection feature and scheduling functions, you must place a remote sensor next to the thermostat. The sensors are able to detect a human presence in different areas. Additionally, you can use the T9 sensors to activate home and away sensors.

You can do this by using the Honeywell Home smartphone app to get a geofence trigger. 

The Resideo industry that manufactured the Honeywell home T9 thermostat mentioned that they specifically designed the system in this way after performing a lot of research and looking through customer feedback. Many clients actually prefer to use a simpler setup than a more complex intelligent setup. 

Additionally, the T9 can only be managed by only using the thermostat, a smartphone or a voice assistant. Users will get access to the usage reports that will be sent out to their emails each month.

The T9 is a really ideal thermostat with a simple, easy to manage interface. It is quite flexible and easy to control.
